🚀 Getting Started

- Use filters to focus on specific types of requests

❓ Frequently Asked Questions
Q: Why does the extension ask for permissions?
A: The extension uses an on-demand permission model for security. It only requests access to specific domains when you choose to analyze them. This ensures your privacy and follows security best practices.
Q: Is my data safe? Does the extension send data to servers?
A: Absolutely safe! All data processing happens locally on your device. Nothing is uploaded to external servers. You have complete control over your data.
Q: Why can't I see some requests?
A: The extension has smart filtering enabled by default to exclude ads, trackers, and other noise. You can adjust filter settings in the extension popup to show more request types.
Q: How do I export captured resources?
A: Use the "Export Resources" button to save all selected resources, or click individual "Save" buttons for specific files. Resources are saved with their original directory structure maintained.
Q: Can I analyze localhost or local development sites?
A: Yes! The extension works with any accessible URL, including localhost, local IPs, and development servers.
Q: The extension isn't capturing some requests. What's wrong?
A: Check your filtering settings. Ensure "Block Ads" and "Block Static" are configured as needed. Some requests might be filtered out to reduce noise in the analysis.
